And snow before you open air conditioning, the machine starts the watch in the gas nozzle of air conditioning (the housekeeper that will be received a fairly thick with the pressure of the air conditioning is in commonly 2.8 MPA

Q:Household air conditioning open is how liquid?

A. Refrigeration condition: Connect the two outdoor pipe cap, valve with a wrench open. With five hexagonal wrench, in fine (high pressure valve) valve mouth, close the valve quickly, in about 20 seconds later turn off the thick valve (low pressure), and then shut down, without electricity. Such fluorine is received outside the machine. It can tear open machine.

Q:Air conditioning is divided into several types

Roughly the fission and window machine. And there came of the changes in temperature and used by, and heat pump, electric auxiliary heating, etc.

Q:Yituo two air conditioning worth buying?

false yituo 2 air conditioner structure is a single power supply, a single compressor, can two indoor machine start and stop alone, cold quantity distribution by distributor of cold energy will be allocated to two indoor machine cooling capacity, cooling process easy to produce cold quantity distribution non-uniform phenomenon, is not convenient to use and maintenance, but the price is relatively low. So consumers in the purchase process, must consultation is clear what type of yituo two, lest be deceived

Q:The development history of air conditioning

In 1902, Dr Carrier invented the world's first air conditioner, is the industry regarded as "the father of air conditioning" and "expert", etc.

Q:Automotive air conditioning and home air conditioning. Whether can be used as cleaning agent

Household air conditioning machine in general are rolling rotor and outlet wall dirty, these two places and wash is ok, evaporator not a professional it is best not to hurt, difficult to reset. Not easy leaking. Thanks LZ adopted.

Q:What is the high pressure and low pressure air conditioning? How to measure?

High pressure compressor exhaust pressure Low pressure of the compressor suction pressure. Usually on the compressor suction and exhaust valve has a special interface, using fluoridated table joins can be measured If is home air conditioning is a little trouble, to see if there is any plunger valve, so, measurement is connected by fluorine list

Q:Install the central air conditioning home?

See how big is your area, If conditional word, of course, your home is the best!

Q:Household central air conditioning wind pipe and more online what is the difference between the good

Central air conditioning wind pipe type, a type of yituo central air conditioning, the biggest wind mill 45 kw, have a fixed frequency and frequency changer, more online, generally for the frequency changer, most large such as gree VRF a host GMV5S pulled 80 machine series, can effect comparing is higher than the wind pipe, up to 6.8:1, screw machine energy saving level. Wind mill advantage is both the size of the room can be installed, small 1 p, 10 square meters room use, fault is lower than more online. Generally installed 10 years of trouble-free operation, many online installation to prevent thunder interference machine operation, complex circuits, fault maintenance costs high, household more online variety, can effect comparing machine has 3.5-6.8, the price expensive is energy saving, wind mill, and more online in machine noise is the same big, installation is the same, the machine without installation position are generally choose more online.

Q:Within the household air conditioning machine evaporator tube temperature sensors have what effect?

Self heating type: protection against the cold wind in the condition of air conditioning heating, in order to prevent the indoor machine out of the cold wind blowing, after startup CPU begin to detect the temperature of the evaporator, when temperature is lower than 22 degrees Celsius, indoor fan motor doesn't work; When the temperature is greater than or equal to 22 degrees Celsius, indoor fan blow down a peg or two, when the tube temperature is greater than or equal to 40 degrees Celsius or compressor running after 2 min, indoor fan according to the set speed running. Heating run against the overload protection: when the CPU continuously 4 s detected tube evaporator temperature greater than or equal to 56 degrees Celsius, outdoor fan stop, when they tested the tube temperature less than or equal to 52 degrees Celsius, the indoor fan.
